My MP gauge on my 59 250 has copper tubing going to it which causes the needle to viberate, can I have a hose built to put in place of the tubbing? Kevin

Kevin,
The copper tubing should not be the cause of your vibration. If you have needle pulsing, then the dampning screw on the MP guage needs to be tightened a bit (it is inside the fitting on the back of the instrument). If your whole guage is vibrating, then you have some excessive airframe vibration, and it would brorbably be a good idea tothink about new engine mount rubbers, and a dynamic prop balance.
